The service will be conducted by the Archbishop of Canterbury, the Most Reverend Justin Welby, who also baptized Meghan and officiated her nuptials to Prince Harry. (Welby also christened Prince George in October 2013 and Princess Charlotte in July 2015.)

Meghan was confirmed immediately following her baptism, which means she is now able to join her husband at Holy Communion.

The Duchess of Sussex was following royal tradition. Kate Middleton was also confirmed into the Church of England in a private service at St. James’s Palace in the weeks leading up to her 2011 marriage to Prince William.
